Influence of radiation quality and additives on the release of bases after ionising irradiation of DNA


DNA and its components irradiated at 300 K as solid samples (X-irradiation under nitrogen atmosphere; heavy ion bom bardment in the beam vacuum) were used to study specificall the direct radiation effect [1]. Heavy ion bombardment with Bi, C, Ti, Xe (all 11.4 MeV/u) and Ni (6.0 and 11.4 MeV/u) gives a modified picture of radiation quality and therefore can… (More)
